Great stuff, probably one of the best I've seen, or should I say heard!!! I'm glad you made that run in between the warehouses, just brutal. As far as sound goes, the current batch of Ferraris might have to take a back seat to the "S".
Do you have a video \ audio clip of that somewhere?
Also we have a couple of owners that put Tubi on their GT's, one of which I drove back to back with the GT-S, and while the Tubi sounds good, its got quite a bit more drone at cruising revs, less rasp north of 4500rpm, and a lot less burbles and pops on the overrun.
I just got the x-pipe installed when the car was in the shop for a pilot bearing issue. Don't have a audio of the car yet. Will look into...
The car does burp and gurgle a lot more now with the x-pipe than with just the Tubi alone (I have had the Tubi on since I bought the car). Honestly. Sounda just like the video clip on the GT-S. Pretty damned tough but not an too annoying or loud. I would expect the Larini rear boxes to put the sound of my car (with the x-pipe) into the annoyingly loud category (for my taste anyway).
